Positive muon spin-rotation (..mu..SR) measurements on GdBa/sub 2/Cu/sub 3/O/sub x/(xapprox. =7) have been conducted in the temperature interval 5.8--300 K. A temperature-dependent relaxation, attributable to Korringa relaxation of the Gd ion, as well as vortex-state relaxation are observed. Magnetic field penetration depths of approximately 1550 and 1900 A (two samples) are extracted from the data. Two muon stopping sites exist for Tless than or equal to80 K, one being associated with normal regions of the sample and the other with superconducting regions.
